The cold work hardening rate of 347 stainless plate steel makes 347 stainless plate steel less machinable than 410 stainless steel, but similar to 304. The table below provides relevant machining data. Carbon can also improve the stress corrosion resistance of austenitic stainless steel 347 stainless plate steel in highly concentrated chloride (such as 42% MgCl2 boiling solution).
